Getting your Arduino online - Using the ESP-01 and Blynk

[@Nicksperiments]

Shouldn’t the ESP 01 have some code flashed to it to communicate to the uno? If I already have code running on the standalone ESP 01 wouldn’t that conflict with communication to the Uno?

[@cabuu4122]

Hi, it should come with the necessary flash but you're right to ask the question as I find it often doesn't or isn't quite right. I've made another video describing how to flash an original copy of the firmware to this device, check it out here: kzbin.info/www/bejne/eXnalKqknJx0o5I

[@szekrenyesbandi6202]

Hi! It's a super tutorial! I just want to ask you, why you need a 10kOhms resistor for the CHPD pin? Thank you in advance!

[@ctbully]

the 10K is a Pullup Resistor, 10K is normally used for this purpose. So that means that it holds that pin on the ESP01 High all the time, which is the Chip Enable Pin.

Excuse me, I get an error in the serial monitor, it says that the ESP-01 is not responding, but I followed all the instructions correctly

[@creativearts4917]

try flashing esp then retry

@@creativearts4917 How we can do it i have the same problem

[@mohamedmagdy-hj6fh]

i am working with esp8266 nodemcu . can i make the same connections to connect it with arduino uno ??

[@Hercules159]

This is will not work if you're starting with ESP-01. You will run into many issues with ESP-01. You need to check if the firmware from Blynk is installed in ESP-01. Then uploading only will work.

[@DigvijayKapdi]

the error " [1609] ESP is not responding " Shows in Serial Monitor, please help me to resolve it. i use arduino Mega and ESP8266-01 wifi module.

[@cabuu4122]

Sorry Digvijay you're error is too generic, please provide more details, what model of ESP are you using, what library versions etc? I'd suggest you try edit the code to identify what is causing the problem or a new ESP-01. Good luck!

[@markuskernocker392]

@@cabuu4122 I am too getting this error. I am using the AZDelivery ESP8266 01 ESP-01. model number AZDeliveryESP826601Sadapter

[@chickenz4604]

change baud rate of the esp in arduino, trial error

[@marcledesmachivite5568]

the best tutorial!

[@cabuu4122]

Thanks so much!

[@wernejo]

What would I need to change in order to get this working on a Wemos ATMega2560? It has a built-in ESP8266 but it acts as a separate board.

[@cabuu4122]

Sorry I don't have any experience of that board but it should be just a case of making sure you have the correct pin outs and updating any libraries as necessary, good luck!

[@SultanSaeed_99]

I connected it like you did put my ESP-01 does not go red,, it just flashes blue when I connect the USB. What could be the problem?

[@jamesb3177]

Check the serial monitor and see if anything further can be revealed there

[@SultanSaeed_99]

@@jamesb3177 It just says "ESP is not responding "

[@cabuu4122]

@@SultanSaeed_99 Sorry not sure, google is your friend though, they'll be someone out there with the same problem, i just looked and this might be a good starting point: community.blynk.cc/t/esp-is-not-responding-error-please-help/19685/7

@@SultanSaeed_99 Hey, I'm getting the same error, did you solved it out??

[@SultanSaeed_99]

Fredi Romo nope I couldn’t get it to work so have you and used the NodeMCU instead

[@irfanfakhruddin3572]

hi, sorry but why my AT says failed to connect to Wifi ?

[@RafaelLopez-yk8qc]

I solved it disconecting the arduino from the computer and then connecting it again, hope it helps.

[@shiwanifasate6813]

Is it OK if I use esp-12e instead of esp - 01 in this project....???

[@crispychickenwing]

hello. wanna ask, why did you connect the rx and tx to other pins instead of the 0 and 1 pin on the arduino?

[@Frank-li8uj]

im wondering that aswell but looking at the replies hes probably not going to reply

[@crispychickenwing]

@@Frank-li8uj I think I got the answer already, not sure if it's right tho, just based on my experience. When I use the tx and rx pin the code won't upload to the arduino, had to disconnect the jumper from these 2 pins first. Pretty annoying so had to choose other pins and set it as TX and rx, not the default one. Only then will the code upload without having to disconnect anything

[@muhammadabidisyraf1753]

@@crispychickenwing i try coding to the esp-01s through arduino uno, the TX RX of esp is connect to TX RX of arduino ( TX(esp) ---> TX(arduino) while RX(esp) ----> RX(arduino) ) and you need to make connection between RST to GND on arduino board

[@kawishsattar8926]

It shows Esp8266 lib.h no such file

[@j.zweistra6502]

will this work with sparkfun redboard to ?

[@cabuu4122]

Sorry I'm not sure about that

[@kungfuboymike1343]

does this work for an Arduino Mega?

[@psjahn]

yes

[@swathisenthilkumar5910]

Can you please name the components used in this project?

[@Karuniaji]

i tried but it didn't work, esp not responding

[@Karuniaji]

nvm i got it working by installing sdk ver 1.5 at blynk community

[@veerand7038]

@@Karuniaji where u got it?

[@Karuniaji]

@@veerand7038 it is a constant struggle, i recommend just use esp32 dev kit, not arduino, arduino nano and uno with esp 01 is bad, doesn't have enough memory and keeps disconnecting

[@ctbully]

What a Half-Arsed attempt this is ! No Code, No demonstration of the code actually working

[@charuzomag-alasin7914]

Is there anyway to do this without using resistors???

[@cabuu4122]

More than likely not, good luck!

[@qazaq6893]

yes you can run it through 3.3v regulator

[@ebaziuk]

So lame, it needs you to make an account with some corporation that then tries to sell you stuff and limits what you can do with your Arduino. This isn't a tutorial it's an ad.

[@cabuu4122]

Blynk was free when this video was made, unfortunately they have since changed their business model.

[@ebaziuk]

@@cabuu4122 Can you recommend a free/open source Android app that can remote control an Arduino with an ESP8266? I have been looking for tutorials like that but I have not found one yet.
